Hello, I'm loozing for a little advise on my next devise purchase. I have been vaping for 4yrs now but have never made the leap to sub ohming. I have decided it is time but I want to make sure the device I choose is safe and reliable. I have narrowed my choices down to MVP Pro 3 or istick pico, I know they are not comparable in size but that's not really an issue for me safety, reliability,and performance are. If anyone out there has owned both devices I would sure appreciate any input.
